This invention relates to lease rods fory warping machines and .has for its primary n, object to provide unitary means whereby the yfrictionial pull imparted to yarn or thread may .be adjusted` A further object of the invention is 'to .pro-4 vide means whereby either of the lease rods;

tilting adjustment of thefheads 7and17-y about the centralaxjisgof. the* supporting""arnis or may be removed and easily re laced.

A still further object of the Invention is toA 0,iprovide a structure which is simple in its conf which, p Y ,l

f 'In operation, the rods 9-are first inserted in struction, positive in its operation and may be inexpensively produced. Y Further objects and advantages will be'- come apparent as 'the description proceedslv Y. reference being had to the accompanying drawings in which; Figure 1 is a side view of the invention; Figure 2 is a plan view;

Figure 3 is an elevation partly in section of the inside of the spring bearing end ofA Figure 2; y

Figure 4 is an outside elevation of the same end as in Figure 3; Y

Figure 5 is an inside elevation partly inf4 .section of the end opposite the spring-bearing rend showing the socket guides; and

Figure 6 is an` outside elevation of the same end showing the adjusting nuts and` showing a dotted line view of one adjustment.

In proceeding in accordance with the pres*-v ent invention, a base or frame plate 1 is 'p'o- 1 vided having upturned portions Zat its endsjf. 'y 'The upturned portions have their outer sides-` guideways 3 in which the bifurcated shanks or supports 4 are movable.f When the proper elevation of 'the Shanks is; obtained, clamping nuts 5 bearing on washers" f6 are provided to hold same in adjusted posi-v tion. Heads 7 and 7 are carried by the.l

ygrooved to form shanks 4 and are provided with sockets 8 and 8 to receive rods 9 vtherein as shown.` The head 7 on one end of the structure has itsv j sockets8 iXed and has U-shaped socket guides lO to assure proper positioning of the rods 9' in the sockets 8. The opposite head 7 is of" tri-part construction, being composed of a central portion carried by the' support or f l I jits sockets, Ya second'head piv'otallylcarried "of i'said Shanks, hinged end 4porshank 4 and two outer portions 11 connected thereto by hinges 11 which hinged, portions ....l' Vfthe latter being fixed-tothe rigid central pore 'tio'n as at 13 while their 11 yielding to allow the rods to have .the spokes s* iorniedffhefeijrig Forum purpose of holding the hinged outerportions position, bowed springs12 are provided,

and bear Vagainst the hinged portions 11.Y

y F or the purpose of'afording angular or 'Shanks ,4, wingl nuts thehinged socket portions or ends of thehead 7 4 and are then moved into position in,l the .head` 7 by the guides 10, the hinged portions be properly positioned. When the rodsare in position the springs 12 act thereon tolmaintain a constant ressure and thereby prevent their 'accts ldenta displacement.

In? narrow fabric weaving and particu-lar- -ly insilk weaving Tof:V narrow fabricsit is i desirable to be able to adjust the rods tovimpart various d'egrees of. 4frictional',resistancre.; to yarn" 'or "thread passing overfthemfj In order -'that l' thisy'may, be accomplished, the heads7 andi"V are. tiltable about. an axis thr i`iglil their centers. The resistance.v to

flnoti'on is thereforeoptional ywith the open-2@ ,'avtor. Further it 'is-desirable' to allow the thread or yarn to pass oi therods in arplane whoseelevation with reference` to the reed of the loom maybe adjusted; for this; reason wing nuts v5 are provided which allowl any? elevation theoperator desires within'theconll'e's of thesupports `4- Having thus' described my invention `what guides, .y bifui-oated` Shanks' slidable in, said guides, locking l means carried .by v said upturned portions andengaging between the` ,furcations of said shanks, a head pivotally outer ends are free I olaim vas newland .desire to vsecure by Letters VlBa-'tentis y j 1 2; f 1.7111'` a vdev iceot the class described,l a base folavingupturned end portions formed-with tions carried by said second head and having sockets, bowed springs carried by said second head and exerting pressure on said hinged portions, means carried by said sup- 5 ports whereby the tiltable adjustment of said heads about their pivots may be Xed, and rods carried in the sockets oisaidheads andimaintainedlin position the@I pressure of saidsprings'. i'
